11 Claims.

This invention relates to improvements in tobacco pipes. The draught orsuction of such pipes is frequently impaired through a clogging whichtakes place at the bottom of the pipe bowl, and particularly at thejunction of the bowl and the pipe stem, which clogging is due to thecontinual accumulation of various ingredients distilled out of thetobacco during the smoking. Those accumulated ingredients have to befrequently scraped out of the pipe-bowl, as, besides impairment of thesuction, they also form hard or viscuous masses which seriously vitiatethe taste of the tobacco.

The principal object of our invention is to provide a tobacco pipe withimproved and-efficient means for remedying the above mentioneddisadvantages.

Another object is to provide a tobacco pipe having simple, inexpensive,reliable, efficient, and improved means for retaining an absorbentmaterial for remedying said disadvantages, and for readily, rapidly, andconveniently discarding and renewing said material.

Other objects and advantages will hereinafter appear.

In the accompanying drawing,-

Figs. 1, 2, 3, 4 are longitudinal cross-sections of tobacco pipesembodying the above referred improvements, all of which forms aremodifications of this invention.

Fig. 5 is a similar view of a tobacco pipe embodying a furthermodification of the invention.

Fig. 6 is a perspective view showing a modification of a detail of theinvention.

The upper portion I of the bowl 2 of the tobacco pipe 3, Fig. 1, isseverable from its lower portion 4 along the plane 5. Between the pipeportions I, 4 is situated an annular framing 6 which is secured to theportion l by means of a flange 1 thereof lodging within a recess 8 inthe underside of said portion, and the framing extending into theinterior of bowl-portion l and having a flared lip 9 which is pressedinto and "from the lower bowl portion 4. A tablet l3, madeot anysuitable absorbent and non-com- ,bustible material, such as mineralfiber, is

frusto-conical in configuration and adaptedto fit into the tapered boreHl'of the framing 6. In the floor i4 of'lowerbowl-portion 4 is located apeg [5 which is threaded thereinto by a shank l6, and said peg serves tohold and retain the tablet H3 in requisite position within the .bore !0against any accidental downward dislocation. When it is requiredtodiscard the tablet l3 for renewal of a fresh tablet, the user maymerely separate the portions 8, 4, by unthreading the former from thelatter, whereby the used tablet :3 will drop out, and a new one may thenbe reinserted and the portion I threaded back upon the portion 4 in theposition shown.

In the modification shown in Fig. 2, the usual pipebowl 2 is provided inits lower portion H with an annular upwardly tapered bore l8, which isadapted to receive the frustro-conical tablet 13 in the manner shown.And said tablet is retainedin this requisite position by means of afitting! which threads into the floor 20 of the pipe bowl and isprovided with a lug 2| upon which the tablet rests. The fitting I9 ispreferably provided with a knurled head 22 for its manipulation. Torenew the tablet l3 it merely requires unthreading of the fitting[9,discarding of the old tablet, reloading the new one, and thenthreading back the saidfitting.

According to the modification illustrated in; Fig. 3, the bowl 2 isprovided with a fire pot or internal secondary bowl 23 which is locatedtherewithin and removably held in place by means of a threaded collar 24thereof screwing into a tapped rim .25 of bowl 2, a rim 26 of bowl 23abutting against the edge of the bowl 2 to limit the internal movementof the fire pot. In the floor 21 of the pct 23 is provided an annulartapered bore 28 adapted to receive the frusto-conical tablet l3 in themanner shown, and a lug 29 formed upon the floor 36 .of thebowl 2projects upwardly and against the underside of the tablet, therebyretaining it in requisite position within the bore 28. To renew thistablet it merely requires unthreading the fire pct 23, discarding theold tablet and recharging the new one, and then replacing the fire potto the position shown.

The modification shown in Fig. 4 is particular- ,ly adaptable forequipping corncob pipes with the improvements of this inventiom as thematerial of such pipes is quite weak. The corncobbowl 2 is provided inits floor 3! with an upwardly tapered bore 32 in which is fitted asimilarly shaped framing v33 adapted to receive the frustro-conicaltablet [3. ,A metallicplate framing 34 consists of a ferrule portion35and a spun threaded shank 36. Said ferrule 35 embraces the exterior ofthe lower end of the corn cob bowl 2, and the threaded shank 36similarly embraces a lug 3! of said bowl surrounding its bore 32, bywhich means the upper bowl portion 2 may be threaded into the lower bowlportion 4, which may be made of any suitable material. The edge 38 ofthe shank 36 is adapted to support the framing 33 against any downwarddislocation.

In the modification shown in Fig. 5, the tablet I3 is sustained in itsrequisite location within the framing 6 by means of a lug i3a formingpart thereof resting upon the floor of the bowl, in the mannerindicated.

Fig. 6 illustrates a modification of the framing 6, in which is provideda plurality of vent grooves 39, whereby an absorbent tablet may beutilized in which the outer conical surface is flush, rather thancorrugated, as illustrated in all the other views.

It will be evident that by the provision of an upwardly frusto-conicaltablet l3 being retained within a similarly configurated pocket of thebowl any accidental dislocation or dropping out of the tablet during useof the pipe will be precluded, and by the provision of a special framingor retaining means 6, 24, or 32, which may be made of metal or any othersuitable non-combustible material, the tobacco pipe will be protectedand a firm and eflicient holding means for the tablet will be at alltimes secured.

With the above provisions the tobacco carried in the pipe above thetablet l3 has its objectionable ingredients distilled out therefrom bythe absorbent material of the tablet. All the clogging of the pipe atthe junction of its bowl and stem is in this manner prevented andimpairment of the suction obviated, and the suction is further improvedby the numerous vents l3b of the tablet [3. With the use of theseimprovements, the bottom of the bowl will be always found dry and freefrom all objectionable hard or viscuous foreign matter which isordinarily found in pipe bowls and vitiates the taste of the smoking.

Variations may be resorted to within the scope of the invention, andportions of the improvements may be used without others.
